1000cc BMW 740i E38 M62 Fuel Injectors

The stock fuel injectors on the BMW 740i E38 M62 are designed for factory power levels. If you're increasing horsepower, running higher boost, or switching to E85 fuel, you'll need higher-flowing injectors to meet the new fuel demands.

Upgrading to 1000cc fuel injectors ensures your engine receives the right amount of fuel, allowing for better throttle response, improved power delivery, and safer tuning.

When it comes to choosing the right 1000cc fuel injectors for your BMW 740i, Excess Injectors stand out. Our injectors undergo rigorous testing and matching processes to deliver superior performance.

What's Included in the Kit?

Each set of 1000cc BMW 740i E38 M62 fuel injectors includes everything you need for a hassle-free installation:

✔ 8 injectors (sold as a matched set)
✔ Pre-installed O-rings
✔ One-piece wiring harness adapter
✔ Height extensions for proper fitment
✔ Tuning data download access

Lifetime Warranty

Worried about reliability? Excess Injectors back their products with a lifetime warranty. If an injector fails due to a manufacturer defect (not contamination or external damage), they will replace it free of charge.

✔ Data stored on the cloud for easy reference
✔ Exact flow and deadtime records allow for a precise replacement
✔ No hassle—just a simple swap to maintain your engine's performance

Tight Testing Controls for Consistent Performance

Every injector set is tested on a custom-built test bench that meets SAE J1832 standards. The testing parameters are strictly controlled to ensure accuracy:

✔ Pressure electronically controlled at 3 bar
✔ Temperature regulated at 21°C
✔ Voltage stabilized at 14V

Because these factors are precisely managed, you get consistent results every time—no variation, no guessing, just reliable performance.

Exact Match Tuning Data

One of the biggest advantages of Excess Injectors is their Exact Match Data system. Unlike generic injectors that require extensive dyno tuning, each set comes with a custom tuning file that's tailored to how your specific injectors performed on the test bench.

✔ Pre-configured tune files available for 11 different ECUs
✔ Each file is uniquely adjusted—no two sets are the same
✔ Saves dyno time and ensures optimal fuel delivery

With this feature, tuning becomes effortless, giving you a perfect air-fuel ratio right out of the box.

Matched for Precision

Excess Injectors don't just flow-match their injectors; they take it a step further by deadtime matching as well.

✔ Dynamically flow-matched within 1%
✔ Deadtime matched within 2%
✔ Over 6,500 flow points tested per injector
✔ More than 265,000 individual measurements recorded per set

These ultra-tight tolerances ensure that all injectors in a set perform identically, giving you smooth engine operation and predictable tuning.

Fuel Compatibility & Build Quality

High-performance injectors need to handle all fuel types, and Excess Injectors deliver with stainless steel internals designed for maximum durability.

✔ Compatible with all fuel types, including pump gas, race fuel, and E85
✔ Stainless steel internal components prevent corrosion
✔ Long lifespan, even with ethanol-based fuels
